Application filed March 6, 1905. Serial No. 248, i40. i

Sandwich, in' the county of Essex, Province 5 of Ontario, Canada, haveinvented certain new and useful Improvements in Door- Locks; andI dodeclare the followin to be a full, clear, and exact description ofthein-f vention, suchas will enable others skilled in I I the art towhich it appertains to make and use the same, reference being had to theaccomp anying drawings, and to the numerals of reference marked thereon,which form a part of this specification.

'15 This invention relates to door-locks; and

it consists in the construction and arrangement of parts hereinafterfully set forth, and pointed out particularly in the claims.

The object of the invention is to providea zo.-lock'whereinthearrangementis such as to render it practically non-pickable, and theparts are so constructed as to require a'key of a peculiar character tooperate the lockbolt,-. the lock being comparatively simple 2 and.inexpensive and the parts of such construction as to render the lockadaptable to p doors of various thicknesses.

The above object is attained by'the structure illustrated in theaccompanying draw- 0 ings, in which Figure 1 is a plan view of the partsof the lock with one side of the lock-case removed, showing the positionof parts when the door is locked and a portion of the door in sec- Fig.2 is a similar view showing theposition of parts when actuated by thekey prior. to the unlocking of the door. Fig. 3 is a plan view of thekey in position for insertion in the lock. Fig. '4 is a similar view of'4 the key, showing the position thereof when inserted in the lock. Fig.5 is an edge elevation of Fig. 4. Fig. 6 is a view in perspective,showing the cylinder of the lock, the sleeves that. embrace the ends ofthe cylinder, the

thimbles that embrace the sleeves and the ,escutcheons that are seatedin the thimbles, said parts being disassembled. Fig. 7 is a sectionalview through the parts of the look, as on line 7 7 of Fig. 1. Fig. 8. isa similar '5 view with the key inserted. Fig. 9 is afragmentary view inperspective, showing the key inserted in the cylinder of the lock. Fig.10 is a perspective view of one of the springactuated dogs or detentswhich assist in securing. the lock-bolt. Fig. 11 is a similar showingthelock-bolt by dotted lines.

The lock illustrated herein is of the type known as mortise-locks, andthe parts are assembled in a suitable case 1.

Located within the casing is the ordinary latch-bolt 2 and its operativeparts, but which do not form any part of this invention and need not bemore specifically mentioned.

Located within the casing is the lock-bolt 3, having channels 4in theopposite faces thereof, which receive the opposed guide-ribs 5 on thesides of the casing, whereby said bolt is firmly held in place anddirected in its movement. Formed upon the upper face of the lock-bolt isa shoulder 6, and adapted to engage said shoulder when the lock-bolt isthrown or projected, as shown in Fig. 1, is a detent 7, which is.normally held in contact with said bolt by the spring 8 and which ispivoted at 9 in the lock-case. Projecting from the under face of thedetent and secured rigidly therein is a lug 10, which passes freelythrough the bolt 3 and lies in the channel 11, formed in the under faceof the lock-bolt and extending longitudinally thereof, the end of saidlug protruding through said lock-bolt and having a curved-face 12.versely of the under face of'the lock-bolt is the key-notch 13,adapted'to be engaged by the wing of the key in actuating said bolt.Also formed in the under face of said lockbolt is the transverse notch15, adapted to receive the locking-dog 16, which is mounted upon theslotted arm 17, pivoted at 18 in the case and actuated by the spring 19to hold said dog in said notch when the door is unlocked and to holdsaid dog in the notch 14 of the lock-bolt when said bolt is projected inthe locked position. The slotted arm 17 is operated to retract thelocking-dog 16 from the notches in the lock-bolt by means of the .key 20when actuating said bolt, as hereinafter explained. The slot 21 in thearm 17 extends from the locking-dog 16 to the end of said arm, thepurpose of which will be hereinafter set forth.

The rotatable hollow cylinder 22 of the view .of the other of said dogsor detents,

Formed translock which receives the key is confined by means of theopposed sleeves 23, which are threaded at 24 to screw through the sidesof the lock-case, as clearly shown in Figs. 7 and 8, the inwardlyprojecting ends of said sleeves embracing the cylinder on each side .ofthe central flange 25 thereof and confining said cylinder so as torotate within said sleeves. Each end of the cylinder 22 is provided withan oblong opening 26 for the insertion of the key, and in the oppositesides of said cylinder are formed the longitudinally-extending slots 27,through which the wings 28 of the key are adapted to extend when inposition to actuate the lock-bolt. Formed through the opposite sidesofthe sleeves 23 are the notches 29, which normally register with theslots27 in the cylinder and allow the opposite ends of the wings of thekey to pass therethrough into operativeposition before the key isrotated in the lock. Fitting over the outer ends of the sleeves 23 arethe thim'bles 30, adapted to slide upon said sleeves to compensate forvarying thicknesses of doors and which are locked to the sleeves bymeans of the notches 31 in said thimbles, which engage over thelaterally-projecting lugs 32 on said sleeves, whereby the sleeves may berotated with said thimbles and by that means screwed into the threadedopenings in the sides of the lock-case or removed therefrom.

The thimbles are countersunk in the opposite facesof the door, as shownin Figs. 7 and 8, and seated within said thimbles are the rotatableescutcheons 33, each having an oblong aperture 34 therethrough for thepassage of the key, said aperture fitting the stem of the key andcausing the escutcheon to rotate as the key is turned. The escutcheonsare confined in place by the door-plates 35, which areprovided withapertures that receive the reduced outer end portions of the escutcheonsand within which said escutcheons-arerotatably retained, as clearlyshown in Figs. 7 and 8.

The character of this look is such as to require a key of peculiarconstruction, such as illustrated in the drawings in this case. Said keycomprises a channeled handle 20, at one end of which are the opposedears 36, between which are pivoted, at 37, the stems 38 of the duplexwings 28, said stems having a shoulder 39, which engages a correspondingshoulder 40 on the handle when the key is straightened after insertionin the lock, whereby the joint between the stems and handle isstiffened. In order to cause the wings of the key to spread in oppositedirections after insertion in the lock, the stems 38 are provided withthe slots 41, which curve in opposite directions and through whichpasses a pin 42, carried by the lower ends of g the links 43, whoseupper ends are pivoted at 44 to the handle, the pin 42 traveling in saidslots as the key is opened and closed. When the key is closed orpartially closed, as shown in Fig. 3, the wings thereof lie together inopposed relation, enabling the key to be inserted through the escutcheonand into the cylinder 22, when upon straightening the handle of the keythe pin 42, riding in the slots 41 as the links 43 draw into alinementwith the handle, will cause the stems to separate, so as to throw thewings of the key apart, as shown in Fig. 4. This movement of the wingswill cause them to pass outwardly through the slots 27 in the oppositesides of the cylinder and through the notches 29 in the sleeves 23, asillustrated in Figs. 1 and 9. With the wings of the key in the positionabove described a rotation of the key will cause one of the wings toengage the end of the lug 10 of the detent 7 and move said.

detent from engagement with the shoulder 6 of the lock-bolt, in whichposition the parts are held as the wing of the key moves in contact withthe curved face 12 of said lug into engagement with the notch 13 of saidbolt. A further rotation of the key will then cause the wing to engagesaid notch and slide the bolt rearwardly, as in unlocking the door. Atthe same time the opposite wing of the key will engage the slotted arm17 and force said arm outwardly, as shown in Fig. 2, thereby retractingthe locking-dog 16 from the notch 14 in the under side of said bolt andpermitting it to move freely. As the key is further rotated to the rightthe Wing of the key engaging the arm 17 will pass therefrom, permittingthe spring 19 to return said arm. and throw the dog 16 into the notch 15in the un der side of the lock-bolt, thereby securing said bolt in itsunlocked position, the detent 7 resting at its free end upon the upperface of the look. It will be noted that the upper and lower edges of thewings of the keys are notched, as shown at 45, and that as the key isrotated. after it is inserted and expanded the opposed. or inner ends ofthe sleeves 23 lie in said notches, while the expanded ends of thekey-stems lie within the cylinder 2-,

clearly shown in Fig. 8, whereby the key is perfectly centered and heldproperly in position while being rotated to manipulate the look. It willalso be noted that the key cannot be expanded until it is turned so asto cause the wingsthereof to register with the notches 29 in the innerends of the sleeves, which are so positioned as to cause the wings tostand transversely of the look when they are projected therethrough.With the parts in their normal or unlocked position the lockbolt may bethrown by turning the key to the left after it has been inserted intothe lock and the wings expanded, which movement of the key will causeone wing to swing the pivoted arm 17 and. retract the (log 16 from thenotch of the lock-bolt and cause the other wing to engage in the notch13 in the under face of the lock-bolt and carry said bolt outwardly tothe locked position shown in Fig. 2, when as the wings of the key passfrom engagement with the arm 17 and the lug 10 of the detent 7 the freeend of said detent will drop into engagement with the shoulder 6 of thelock and the dog 16 will enter the-notch :14 in theunder side'of thelockbolt,.whereby said bolt isfirmly held and can only be moved tounlockthe door. after the detent 7 has been raised to free the shoulder.

inthe endfthereof and through the opening 34 inthe escutcheon. I

It will now be understood that this lock can only be manipulated bymeans of a key of'the peculiar construction shown and that said lockcannot be picked by the insertion of a Wire or other instrument, owingto the fact I that the only entrance into the look through theescutcheon is by way of the slots 27 in the.

cylinder 22, which as said cylinder rotates is partially cut ofiby theembracing walls of the ends of the sleeves, leaving only a smallcentralopening through the walls of the cylinder that will scarcelypermit of the introduction of a wire or other tool, and as said centralopening in the sleeve is indirect alinement with the channel 11, in theface of the lock-bolt and the slot 21 in the arm 17 neither of saidparts could be actuated by the end of a wire passed through said centralopening, as said wire would only enter said channel or slot, and as thelug 10 is quite pointed .at its end it does not afford any op-'portunity of raising the detent by the use of any instrument, except a:properly-constructed key, as herein shown.

Having thus fully set forth my invention,

' what I claim as new, and desire to secure by Letters Patent, is
